Question

I have two scripts, a python script and a perl script.

How can I make the perl script run the python script and then runs itself?

Answer 1

Something like this should work:

system("python", "/my/script.py") == 0 or die "Python script returned error $?";

If you need to capture the output of the Python script:

open(my $py, "|-", "python2 /my/script.py") or die "Cannot run Python script: $!";
while (<$py>) {
  # do something with the input
}
close($py);

This also works similarly if you want to provide input for the subprocess.
